Ce que signifie cette interaction, en termes simples

Aprepitant and Carbamazepine can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Aprepitant belongs to Gastrointestinal Tract; Carbamazepine belongs to Central Nervous System.
